Looks like Philadelphus to me too. Mine is in full flower now and smells heavenly!
Those pictures are of perennial oriental poppies, not annual opium poppies. Lovely, though!
Some Osteospermums are sold as bedding plants and are a bit tender - they are from South Africa. Others are garden perennials and seem to survive all but the harshest winters. I've got one (the ordinary purple kind) that has lived with me since 1980!
Chrissy, you beat me to it! I agree.
Can we see a photo? Perhaps it's not Philadephus!
Yes, Hypericum androsaemum or Tutsan. It has lovely colour-changing berries later on.
Not Black Bryony, that has shiny leaves, but might be Black Bindweed, Fallopia convolvulus. It's hard to tell how big the leaves are from the photo.
Ivy and creeping buttercup. Terrified of ground elder getting in!
Yes, it looks like Tansy to me too - Tanacetum vulgare.
Sorry KT53 but I totally disagree with your statement. Of course workers should read every sign, it could be life or death!
